燃气管网事件的故障树比较与构建

Comparison and Construction of Fault Trees for Gas Pipeline Events

对燃气事故原因进行分类,科学、规范地统计和管理事件记录,是探讨事故防范与应对措施的前提,也是燃气行业管理和燃气供应企业共同关注的问题。在对燃气管网各类故障树比较分析后,本文构建的"人-物-环"三因素故障树,特别适用于燃气供应企业进行管网事故归因分析。

Classifying the causes of pipeline accidents, managing and analyzing accident records with theoretical basis and standard, is the premise of improving accident prevention and response, and so is a hot topic focused by gas supply enterprises and gas safety management organizations. After comparing a few fault tree models established by previous researchers and organizations, a new fault tree model based on 3 factor model： People-Equipment-Environment is introduced. The new model is especially suitable for gas supply enterprises to analyze the causes of pipeline network accidents.
